Description

  The present invention relates to chopsticks used for meals, and more specifically, it is not easy to use with an improper holding method, it is easy to learn the habit of using it with the correct holding method, and it has the original shape of chopsticks It is related to chopsticks that the user can use without a sense of incongruity.

  Chopsticks are tools that cleverly move two rods to pinch food between the ends of the rods. There are wooden, bamboo, lacquered, synthetic resin, metal, etc. Asia including Japan Widely used in countries. However, handling of chopsticks when picking up food and carrying it to the mouth requires delicate manipulation of the strength of the fingertips. For this reason, it is not easy for infants and children to use chopsticks in the correct way for those who do not have the habit of using chopsticks, such as Westerners. In particular, in recent years, for example, young people and the like have often seen unauthorized use, such as using chopsticks crossed, and are often regarded as social problems.

  Conventionally, various chopsticks and instruments used for learning how to properly hold them have been proposed as disciplined chopsticks. For example, as these chopsticks and instruments, chopsticks with a corrective instrument attached (for example, see Patent Document 1, hereinafter referred to as prior art 1), or chopsticks with a thumb recess (for example, Patent Document 2 (hereinafter referred to as “Prior Art 2”).

JP 2002-341747 A Japanese Utility Model Publication No. 07-011711

However, in the above-described prior art 1, the correction tool must be attached to the chopsticks when used, which is complicated. During meals, for example, when handling dishes or seasonings with a dominant hand, chopsticks may be placed on the table, but the chopsticks can be fixed to the fingertips by passing the thumb through the corrective tool. In such a case, each time a chopstick is placed, the corrector must be attached and detached, which is extremely complicated.
In addition, some of the above correction tools are formed integrally with the chopsticks, but in this case, the chopsticks have a shape far away from the original rod-like body, which makes the chopsticks uncomfortable and uncomfortable for the user. Is natural. In addition, in this case, there is a problem that the chopsticks cannot be easily washed because the correction tool is integrated.

  On the other hand, in the above prior art 2, the position of the thumb with respect to the chopsticks is specified, but this alone does not specify the position and posture of the other fingers with respect to the chopsticks. Absent. In addition, when holding a chopstick, the thumb presses the chopstick from an oblique direction, not from a right angle, so the positions of the pair of chopsticks that the thumb strikes are different from each other. For this reason, if the concave portion is formed at the same position on both chopsticks, there is a problem that the chopstick tips cannot be aligned when held in the correct way.

  The technical problem of the present invention is to solve the above problems, it is not easy to use with improper holding, it is easy to learn the habit of using with the correct holding, and the original shape of chopsticks It is to provide a chopstick that is provided and can be used by the user without a sense of incongruity.

In order to solve the above-described problems, the present invention is configured as follows, for example, based on FIGS. 1 to 6 showing an embodiment of the present invention.
That is, the present invention relates to chopsticks, and is composed of a pair of rod-shaped bodies (2 and 2). Each rod-shaped body (2) has a chopstick tip (3) formed at one end thereof, and each rod-shaped body (2 ) Is provided with a gripping portion (4) to be gripped in use at the intermediate portion in the length direction, and each rod-like body (2) has at least a cross section of a portion including the gripping portion (4). The shape is formed in a substantially triangular shape, and the chopstick tip part (3) side of the grip part (4) is tapered toward the chopstick tip part (3). And

  The gripping part of the chopsticks has a substantially triangular cross section, and is a substantially triangular prism. However, it does not have any other objects or recesses, and has a rod shape that approximates the original shape of the chopsticks. It is a body. For this reason, this chopstick is used without causing the user to feel uncomfortable.

When holding the above rod-shaped bodies in the correct manner, for example, as shown in FIG. 3, the rod-shaped body positioned on the lower side (hereinafter also referred to as “static chopsticks”) has a chopstick tip side of the gripping portion as a ring finger. It is supported so that the side opposite to the chopstick tip is sandwiched between the crotch part between the thumb and the index finger, and the middle of both supports is pressed by the thumb and supported at three points.
On the other hand, the rod-shaped body located on the upper side (hereinafter also referred to as “moving chopsticks”) is supported by the tip of the index finger and the middle finger on the chopstick tip side of the grip part, and the second joint of the index finger on the opposite side of the chopstick tip part. And the root joint, and the middle of both supports is supported near the tip of the thumb and supported at three points.

The crotch part between the thumb and forefinger that sandwiches the chopsticks is V-shaped when supporting the chopsticks, but the cross-sectional shape of the chopsticks is approximately triangular. Since it is a substantially triangular prism, it is securely held in the finger crotch between the thumb and forefinger, and is firmly supported.
In addition, the above-mentioned moving chopsticks are supported in a stable and reliable manner in three directions on each surface of the substantially triangular prism by the three fingertips of the index finger, the middle finger and the thumb. For this reason, each finger is correctly placed on both chopsticks, and it is easy to learn how to hold it correctly.

  The portion to be gripped of the chopsticks is a substantially triangular prism. For example, as shown in FIG. 4, when each chopstick is to be securely held with three fingers or the like, the direction of the ridge line portion in the circumferential direction is specified. For this reason, for example, if the chopsticks are held in an illegal manner such that they cross each other, the moving chopsticks and the stationary chopsticks come into contact with each other through the ridgeline, and the posture of the moving chopsticks becomes unstable. As a result, the chopsticks cannot be easily used with this illegal holding method.

  Here, the cross-sectional shape of the portion including the grip portion may be a substantially triangular shape and may be a shape with a sharp corner, but is a substantially triangular shape in which the middle portion of the side is expanded outwardly, If the ridgeline formed by the corners of a roughly triangular shape is rounded and chamfered, the circumference of the rod-shaped body will not be rounded. It is preferable because it makes gentle contact.

  The chopsticks may be formed in a tapered shape from the other end opposite to the chopstick tip to the chopstick tip. However, if the end portion on the opposite side of the chopstick tip portion to the grip portion is formed to have the same thickness, depending on the size of the hand, the length of the finger, or the user's preference, the grip portion Even if it deviates in the length direction of the chopsticks, it is preferable because it can be used easily with the correct way of holding.

  The thickness and length of the rod-shaped body, the position of the gripping portion, and the like are not limited to specific dimensions. However, it is preferable that the length dimension from the grip portion to the end portion on the side opposite to the tip portion is 40 to 60% of the total length of the rod-shaped body because it is possible to specify a range to be gripped with the correct holding method.

  The cross-sectional shape of the chopstick tip is not limited to a specific shape, and may be, for example, a substantially triangular cross-sectional shape continuous from the grip portion. However, for example, as shown in FIG. 4, the ridgeline of the moving chopsticks and the chopsticks at the gripping part is shifted from the line connecting the centers of the two chopsticks. There is a case where it cannot be pinched stably. On the other hand, if the cross-sectional shape of the chopstick tip is a polygon having four or more sides, food can be sandwiched stably at the chopstick tip regardless of the orientation of both chopsticks at the grip. The cross-sectional shape of the chopstick tip part is preferably circular, which is more preferable because food can be sandwiched more stably by the chopstick tip part.

  The above-mentioned chopstick tip can be formed in any shape, but anti-slip processing is applied by forming other numbers of fine protrusions or annular grooves on the surface in the vicinity of the chopstick tip. It is preferable because food can be sandwiched stably.

  The rod-shaped body is not limited to a specific material, and may be formed of any material such as wood, bamboo, lacquer, synthetic resin, metal, etc. If it exists, it has moderate rigidity and flexibility, and since it has moderate frictional force, it is easy to pinch food and can be processed at low cost.

  Since the chopsticks of the present invention are configured and act as described above, the following effects can be obtained.

  (1) Since the cross section of the gripping part is substantially triangular, when used in an improper way of holding, for example, crossed chopsticks, the posture of the chopsticks is not stable and cannot be used easily. On the other hand, if the chopsticks are held in the correct way, the fingers are correctly placed, and both the stationary chopsticks and the moving chopsticks can be supported stably and securely by these fingertips. As a result, by using the chopsticks, it is possible to naturally and easily acquire the habit of using the chopsticks properly.

  (2) The part including the above gripping part is merely a triangular prism, and it is a rod-like body that approximates the original shape of chopsticks without attaching other objects or forming concave parts. ing. As a result, the user can use the chopsticks without feeling uncomfortable, and can easily wash the chopsticks in the same way as ordinary chopsticks.

  (3) The cross-sectional shape of the portion including the gripping portion is a substantially triangular shape in which the middle portion of the side is expanded outward, and the ridgeline formed by the corner portion of the substantially triangular shape is rounded and chamfered. For this reason, it is preferable because it approximates the original shape of the chopsticks and does not feel more uncomfortable, and it makes gentle contact with the soft fingertips of infants and children.

  (4) If the above-mentioned gripping part and the other end are formed in the same thickness, the gripping part may be in the length direction of the chopsticks depending on the size of the hand, the length of the finger, or the user's preference. Even if it deviates, it is preferable because it can be easily used with the correct holding method.

  (5) It is preferable that the length dimension from the gripping portion to the other end is 40 to 60% of the total length of the rod-shaped body because the range of gripping in the correct way can be specified.

  (6) When the cross-sectional shape of the chopstick tip is a polygon having four or more sides, it is preferable that food can be sandwiched stably at the chopstick tip, and the cross-sectional shape of the chopstick tip is circular. It is more preferable that food can be sandwiched more stably at the chopstick tip.

  (7) It is preferable that the surface in the vicinity of the chopstick tip part be subjected to anti-slip processing because food can be sandwiched stably.

  (8) It is preferable that the rod-shaped body is made of wood or bamboo because it has moderate rigidity and flexibility, and also has moderate frictional force so that food can be easily caught and can be processed at low cost.

It is a perspective view of a chopstick which shows the embodiment of the present invention. FIG. 2A is an enlarged cross-sectional view of a gripping part and a chopstick tip part of a chopstick according to an embodiment of the present invention, FIG. 2A is an enlarged cross-sectional view taken along line AA in FIG. 1, and FIG. It is a BB line arrow expanded sectional view. It is a perspective view at the time of holding the chopsticks in the correct way of embodiment of this invention. It is sectional drawing of the chopsticks when holding in the correct way of embodiment of this invention. It is a perspective view at the time of holding chopsticks in an improper way of the embodiment of the present invention. FIG. 6 (a) is a perspective view of a chopstick, and FIG. 6 (b) is an enlarged sectional view taken along the line CC of FIG. 6 (a).

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
As shown in FIG. 1, this chopstick (1) consists of a pair of rod-like bodies (2, 2), preferably made of wood or bamboo, and even if lacquered, etc., if desired. Good. However, the chopsticks of the present invention are not limited to these materials, and may be made of synthetic resin, for example.

  The rod-like body (2) has a chopstick tip (3) formed at one end thereof, and a grip (4) gripped during use in the middle in the length direction. The length dimension (L1) from the gripping part (4) to the end part (5) opposite to the chopstick tip part (3) is preferably 40 to 60% of the total length (L) of the rod-like body (2). Specifically, for example, it is set to about 50%.

  The rod-like body (2) is formed in the same thickness from the end (5) opposite to the chopstick tip (3) to the part including the grip (4). The chopstick tip part (3) side of the grip part (4) is formed in a shape gradually tapering toward the chopstick tip part (3).

As shown in FIG. 2 (a), the portion including the grip portion (4) has a cross-sectional shape formed in a substantially triangular shape in which the middle portion of the side is expanded outward, and the corner portion of the substantially triangular shape is formed. The ridge line (6) to be formed is rounded and chamfered. It should be noted that the degree of swelling of the middle portion of this side, the radius of curvature of the chamfered ridgeline (6), and the like are not limited to specific dimensions.
On the other hand, the chopstick tip (3) has a circular cross section as shown in FIG. 2 (b). As shown in FIG. 1, the surface in the vicinity of the chopstick tip (3) is provided with an anti-slip process (7) composed of fine convex portions.

  When holding the chopsticks (1) in the correct way, as shown in FIG. 3, one stick-like body (2a) has a ring finger (8) on the chopstick tip (3) side of the gripping part (4). The side opposite to the chopstick tip (3) is supported by the finger crotch (9) between the thumb and forefinger, and the middle of both supports is held by the thumb (10). It is surely supported three points. The rod-like body (2a) located on the lower side is also referred to as a “static chopsticks” because there is little movement when sandwiching food. On the other hand, the other rod-shaped body (2b) located on the upper side is supported by the tip of the index finger (11) and the middle finger (12) on the chopstick tip (3) side of the grip portion (4), and the chopstick tip The side opposite to the part (3) is supported between the second joint and the base joint of the index finger (11), and the middle of both supports is pressed near the tip of the thumb (10) and supported at three points. . The other rod-shaped body (2b) is also called “moving chopsticks” because it operates to sandwich food.

  The grip part (4) is formed in a substantially triangular cross section, but the finger crotch part (9) between the thumb and the index finger is substantially V-shaped so that the chopsticks (2a) can be attached to the grip part (4). Since it is pinched, the gripping part (4) of the chopsticks (2a) is securely held in the finger crotch part (9) and firmly supported. Further, as shown in FIG. 4, the moving chopsticks (2b) have three flat surfaces of the grip part (4) having a substantially triangular cross section, and the index finger (11) and the middle finger (12). The three fingertips with the thumb (10) are stably and securely supported from three directions. As a result, the fingers for the above-mentioned chopsticks (2a) and moving chopsticks (2b) are correctly placed, and the chopsticks (1) have a stable posture with the correct way of holding, and each chopstick tip (3) is easily used Is operated as intended. Since the chopstick tip (3) is provided with a non-slip process (7), food can be handled more easily by the chopstick tip (3).

  The cross-sectional shape of the grip portion (4) is a substantially triangular shape in which the middle portion of the side is expanded outward, and the ridge line (6) is rounded and chamfered, so that the rod-like body (2) is rounded as a whole. It is tinged and gently touches even the soft fingertips of infants and children, and can be handled easily without causing a sense of incongruity as chopsticks (1).

  When the above chopsticks (1) are used in the way of holding so-called crossed chopsticks, for example, as shown in FIG. The moving chopstick (2b) comes into contact with the ridge line (6). As a result, the posture of the moving chopsticks (2b) becomes extremely unstable in this improper way of holding, and the chopsticks (1) cannot be easily operated. Therefore, it becomes difficult for the user to use the chopsticks (1) with this illegal holding method, and the correct holding method is naturally worn.

In the above embodiment, the cross-sectional shape of the chopstick tip (3) is formed in a circular shape. However, in the present invention, the cross-sectional shape of the chopstick tip may be formed in other shapes.
For example, in the modification shown in FIG. 6, the cross-sectional shape of the chopstick tip (3) is formed in a hexagonal shape with rounded corners. In this modification, even if the circumferential position of the chopsticks (2a) and the moving chopsticks (2b) is firmly fixed with the fingertip, the peripheral surface of the chopstick tip (3) has six flat portions and six Since there is a corner portion, there is an advantage that food can be easily sandwiched between the chopstick tips (3). The other shapes and structures of the chopsticks (1) are the same as those in the above embodiment and operate in the same manner, so that the description is omitted.

  The chopsticks described in the above embodiments and modifications are illustrated to embody the technical idea of the present invention, and the shape, dimensions, structure, etc. of each part are limited to those in this embodiment and modifications. Instead, various modifications can be made within the scope of the claims for utility model registration of the present invention.

For example, in the above embodiment, the cross-sectional shape of the portion including the grip portion is formed into a substantially triangular shape in which the middle portion of the side is inflated to the outside. The corner of the substantially triangular shape may be rounded, and the corner of the substantially triangular shape may be rounded.
In the above embodiment, the end from the side opposite to the chopstick tip is formed to have the same thickness as the grip. However, in the present invention, the end opposite to the chopstick tip is provided. May be formed into a shape that gradually becomes thinner toward the chopstick tip.

In the above-described embodiment, the chopstick tip is provided with an anti-slip process consisting of fine convex portions. However, in the present invention, the anti-slip process of another structure may be applied to the chopstick tip, or the anti-slip process may be omitted.
Furthermore, the thickness and length of the rod-shaped body and the position of the gripping portion are not limited to those of the above-described embodiments and modifications, and can be set as appropriate according to the size and preference of the user's hand. Moreover, the material of this rod-shaped body is not limited to that of the above-described embodiment, and it is needless to say that an arbitrary treatment such as lacquering may be applied to the surface, and addition of colors, patterns, etc. can be arbitrarily set. .

  The chopsticks of the present invention are not easy to use in an improper way of holding, can easily acquire the habit of using in the correct way, and have the original shape of chopsticks, so that the user does not feel uncomfortable Since it can be used, it is particularly suitable as a chopstick for use by infants and children, but it is also suitable as a chopstick for use by adults.
